T0 aZZ whom it may concern:

Be it known that I, WILLIAM Fox, a citizen of the United States,residing at Detroit, in the county of Wayne and State of Michigan, haveinvented a new and useful Improvement in Processes of ProducingDecorative Effects on Glass, of which the following is a specification.

The object of the invention is to supply an improved process by whichdecorative effects on glass may be obtained.

I am, of course, aware that at the present time decorative effects areobtained on glass. It has however been the custom to first prepare theglass with a special solution and then to apply special coloring, orelse to apply the coloring and then either burn it, or dissipate it witha solution in order to produce the desired effect.

In the present invention I apply the coloring matter to the reverse sideof dry clean glass and effect the blending by the applica tion of airfrom varying angles. Thus one of the objects of my invention is tosupply a simplified process by which artistic effects can be obtained.

With this and other objects in view my' invention I is hereinafter morefully described and claimed:

I first obtain ordinary oil paints of vary ing shades, such as red,white, yellow andblue, each of which should be thoroughly mixed and ifthere is any sediment I prefer to strain the paint. I then take a dryclean piece of glass, onto the reverse side of which I apply my paint.For this purpose I procure a small pointed piece of wood, camel hairbrush or the like. This Idip into one of the colors and deposit a dropon the reverse surface of the glass. I then drop a11- other drop ofanother coloronto the first drop, or close beside it, and perhaps athird drop onto the two previous drops or close beside them. I thenproject air from vary ing angles, preferably through a flexible tube,towards the colors so as to cause them to intermingle and blend. Whenthe colors have been sufliciently dissipated I apply another drop of anydesired color which I blend with those already applied as previ ouslydescribed. I usually commence working at one edge or corner of the glassso that I may continue to work from the colored portion Withoutpossibility of part of ithaving dried before the adjoining portion iscolored.

Application filed; time 13, .1924. t rmini)- 719,743..

Broadly spealriiig Iiprefer to superimpose my colors rather than placethem on an adjoining portion of the surface yet uncolored for in thisway I find that better blending can be effected; and Whereas, throughoutmy description I haveused the work color I find that a judiciousapplication of white paint with the colors will add to the effect.

When the whole of the surface of the glass has been colored'it willpresent an indistinguishable mass of color on the reverse side of theglass to which the paints have been applied. But when turned over andlooked at through the glass, not only will there be a great number ofvarying colors, and

shades of color, far in excess of the number very good results may beobtained by blowing with the mouth. I/Vhile I can accom plish my objectby using cool dry air supplied by bellows or the like, the resultsobtained are inferior. This is attributable to the fact that the warmthand moisture affect,

the paints and cause better and more thorraresnzr o ough blending. Theagatelike and mottling eifects are of course obtained by the applicationof the air from constantly varying angles.

lVhen the coloring has been completed over the whole surface, I applyvarnish or other adheslve material and therewith secure a protectivecovering of paper, canvas or other protective material to the paintedsurface of the glass, for 1t Wlll be remembered that the paint has beenapplied to the reverse Having thus described my invention what I desireto secure by'Letters Patent is:

1. A process of producingxdecorative effects' on glass comprisingapplying drops of paint'of various colors on the reverse side of dryclean glass and'applying air thereto 5 from varying angles. I i

2. A process of producing decorative effects on glass comprisingapplying drops of paint of Various colors on the reverse side 7 of dryclean glassand blowing warm moist air on said paint from constantlyvarying 10 angles. I

In testimony whereof I afiix my signature inthe presence of twoWitnesses at Majestic Building, Detroit, Michi an.
